    NAVCOMTELSTA Far East was originally designated as Naval Communications Facility, Yokosuka Japan and was commissioned on 8 January 1951 after the outbreak of the Korean Conflict. In December 1952, U.S. Naval Radio Receiving Facility, Kami Seya, Japan was completed and the Security Group Department and general service receivers were moved to Kami Seya. During the Korean Conflict, the rest of NAVCOMMFAC Yokosuka moved to Kami Seya. In 1960, the command was redesignated U.S. Naval Communications Facility Japan and relocated to Yokosuka Japan. The following year, the command was again redesignated as U.S. Naval Communications Station, Japan. This name stood for 30 years until 1991, when it was changed to U.S. Naval Computer and Telecommunications Station, Japan to acknowledge the increasing reliance on computers and telephones in telecommunications. Also in 1991, NTCCs Atsugi and Sasebo and NAVCOMM Dets Okinawa and Misawa were functionally transferred to NAVCOMTELSTA Japan. 1993 saw the transfer of Base Communications Offices (BCOs) at Atsugi, Sasebo and Yokosuka to NAVCOMTELSTA Japan. Then in 1995, another name change to U.S. Naval Computer and Telecommunications Station, Far East occurred with the functional transfer of the Communications Department from Commander Fleet Activities Chinhae, Korea to this command and the establishment of NAVCOMM Det Chinhae.
